Fibre-lyte have the SWB chassis & top-deck on file.... unfortunately I don't think they can supply the 'white' coloured GRP material so would have to out-source this to send it to Fibre-lyte for cutting (there was another thread on this forum about suitable suppliers)
Of course you will need a shorter main drive belt, which you might be able to get made up from a specialist belt-drives factors.
Ebay & RC10Talk member 'Mr Lexan' also does excellent reproductions of the SWB shell
P.S; I too love the shell on your first car, very retro & for some reason reminds me of of the Phil Davies colour scheme/design, CATS are great cars but i'm afraid unless I get lucky they are too costly for me
